1.3 Basic AT Command Processing Principles
1.3.1 Ports
The ME909u-521 module provides three ports to interact with its host:
MODEM port: simulated using USB, for AT command interaction and
establishing data connection.
Port name: HUAWEI Mobile Connect-3G Modem
PCUI port: simulated using USB, for AT command interaction only.
Port name: HUAWEI Mobile Connect-3G PCUI Interface
ECM port: simulated using USB, for establishing communication connection.
Port name: CDC Ethernet Control Model (ECM)
The ME909u-521 also provides a port for debugging:
DIAG port: Simulated using USB, for DIAG (diagnostic) command interaction
(mainly used to debug modules at present).
Port name: HUAWEI Mobile Connect-3G Application Interface
A host controls a module using AT commands. If AT commands are unavailable, a
module can be deemed as unavailable.
1.3.2 AT Command Processing Mechanism
A module processes AT commands from the ports (MODEM, PCUI) in series. An AT
command can be processed when and only when the previous AT command
processing has been completed. If the module is processing an AT command, a new
AT command from the same port will be ignored and other commands from other
ports will be buffered until the current AT command is processed.
This rule also applies to COM ports converted from USB ports.
The processing of an AT command starts when the AT command is entered from the
TE, and ends when the UE (the module) returns all the results in response the
command.

All AT commands entered during
this period of time will be
ignored.
All AT commands entered
during this period of time will
be ignored.
Some special AT commands can be aborted by new AT commands. Such special
commands are called abortive commands.
The ME909u-521 supports the following abortive AT commands:
The AT+COPS Set command
AT+CLCK

12
Example:
AT+COPS=1,2,23415
OK
Before the results ofAT+COPS
is returned, enter any characters
(such as"AT"), the module will
terminate the processing of
AT+COPS and returnOK. The
entered characters are used to
abort the command only .
Some commands can be executed when SIM card is inserted. It would return to SIM
failure if SIM card is not inserted. For more information, see Property Description of
related AT in HUAWEI ME909u-521 LTE LGA Module AT Command Interface Specification.
Example:
AT+CREG?
+CME ERROR: SIM failure
Note:
SIM failure indicate that SIM card is not inserted.
1.3.3 Recommended Timeout Mechanism for AT Commands
Processed by a Host
A module processes AT commands in series. Do not send another AT command
before the result for the current command is returned or the current command times
out (except when the current command is an abortive AT command). The following
table lists AT command timeout durations (starting from the time when an AT
command arrives at a port).
Table 1-1 AT command timeout duration
AT Command
Timeout Duration
General AT commands
30s
AT+CMSS/AT+CMGS (used to send text
messages)
60s
AT+COPS=? (used to search for networks)
120s
After an AT command times out, it is recommended that the host check whether the
module is functioning normally. The following procedure is provided for your
reference:
1. The host sends AT to the module.

13
2. If the module returns failure information, go to step 5.
3. If the module returns success information, the module is functioning normally.
4. If the host times out (the host waits for a response for over 30 seconds) three
times when waiting for the response from the module, go to step 5. Otherwise go
to step 1.
5. The host deems that the current module does not exist or is unavailable. Close
the port, stop sending all AT commands, exit the procedure to determine
whether the module is normal, and re-search for modules.
